Vaxart, Inc. (VXRT)·Q4 2024 Earnings Summary
Executive Summary
- FY24 revenue rose to $28.7M (from $7.4M in 2023) on BARDA-related government contracts; FY24 net loss narrowed to $66.9M ($0.33/share) vs $82.5M ($0.57/share) in 2023 . Q4 revenue is implied at ~$15.19M (FY less 9M), with Q4 net loss implied at ~$12.0M (FY less 9M) as BARDA funding ramped late in the year .
- COVID-19 Phase 2b: 400-person sentinel cohort completed in Dec-2024; DSMB recommended proceeding without modification in Jan-2025, but on Feb 21, 2025 the U.S. government issued a stop-work order pausing the 10,000-participant portion pending further decision within 90 days (follow-up on the 400-person cohort continues) .
- Norovirus: Initiated Phase 1 trial in Mar-2025 to test second-generation constructs head-to-head vs first-gen, with topline data as early as mid-2025; complete Phase 1b data in elderly published in Science Translational Medicine showed strong mucosal/systemic immunogenicity and favorable safety .
- Liquidity and runway: Cash, cash equivalents and investments were $51.7M at 12/31/24 with runway into 4Q25; management implemented ~10% workforce reduction after the stop-work order and is exploring partnerships/non-dilutive funding. Key near-term catalysts: resolution of stop-work order and norovirus Phase 1 readout .
What Went Well and What Went Wrong
-
What Went Well
- DSMB safety green-light: “an independent DSMB … recommended that the study continue without any modifications” for the 400-patient COVID-19 sentinel cohort; FDA review ongoing .
- Norovirus advancement and data: Phase 1 trial of second-gen constructs initiated; published elderly Phase 1b data showed “strong and durable antibody responses” including mucosal IgA in saliva and nasal cavity; vaccine was well tolerated with only mild-moderate solicited events .
- CEO tone on platform: “Our candidates have demonstrated … long duration of protection … and importantly, a benign safety and tolerability profile” across 19 trials/7 viruses, reinforcing the differentiation of mucosal, oral pill vaccines .
-
What Went Wrong
- COVID-19 trial uncertainty: Stop-work order on Feb 21, 2025 halted the 10,000-participant portion of the BARDA-funded Phase 2b study; Vaxart has not been provided a reason; decision to cancel/extend/terminate expected within 90 days .
- Cash runway shortened: Guidance moved from “into 2026” (as of Q3) to “into 4Q25” at year-end, accompanied by ~10% workforce reduction after the stop-work order .
- Estimates context: Street consensus for Q4 2024 revenue/EPS was unavailable via S&P Global, limiting beat/miss assessment versus expectations (see Estimates Context) (Values retrieved from S&P Global)*.

Earnings Call Themes & Trends
Management Commentary
- CEO on platform differentiation: “Our candidates have demonstrated … reduction in viral transmission and shedding, long duration of protection … and importantly, a benign safety and tolerability profile. Across 19 clinical trials … our vaccine candidates have shown favorable safety data.”
- CEO on stop-work order approach: “We recognize and appreciate the importance of oversight … and we are committed to working collaboratively with … HHS, BARDA … as they evaluate … the 10,000 participant portion of the Phase 2b study” .
- CSO on second-gen norovirus constructs: “Through the power of machine learning, we created new … constructs … designed to express the antigenic protein at higher levels in the intestinal space … [with] substantially improved immune responses compared to our first generation constructs” .
- CMO on elderly data: The vaccine “generated robust and durable systemic antibody responses … [and] strong and durable IgA responses in the saliva and the nasal cavity … [and] was safe and well tolerated” .
- CTO on manufacturing/shelf life: “We maintain our own GMP manufacturing facilities … shelf life is expected to last for two years” .
Q&A Highlights
- Norovirus construct and endpoints: Phase 1 enrolls ~60 adults 18–49 across dose cohorts; immunogenicity readouts will focus on serum norovirus blocking antibody assay (NBAA) titers and fecal IgA, which correlated with protection in the challenge model .
- Translational potency: Second-gen constructs showed stronger immune responses in animals; management expects even small human increases could materially improve protective efficacy based on modeling .
- Sentinel cohort/Regulatory: DSMB recommended proceeding with no modifications; FDA received the same 30-day safety data; manufacturing in place to support continuation if authorized .
- Market opportunity/competition: Management highlights ~$10B U.S. annual economic burden of norovirus and believes an oral option will be competitive even as large players pursue injected candidates .
- Funding/partnerships: Company is engaging multiple parties for partnerships and non-dilutive funding; will update when appropriate .
Estimates Context
- Street consensus for Q4 2024 revenue and EPS was unavailable via S&P Global; therefore, we cannot assess beats/misses versus estimates for the quarter. Management did not provide formal numeric guidance for revenue/EPS, limiting forward estimate anchoring (Values retrieved from S&P Global)*.
Key Takeaways for Investors
- Safety de-risking achieved on COVID program (DSMB positive), but program visibility depends on resolution of the federal stop-work order; any favorable decision would be a material catalyst .
- Norovirus is the clearer near-term value driver: Phase 1 underway with topline as early as mid-2025; recent peer-reviewed elderly data bolster the mucosal platform case .
- FY24 revenue inflected on BARDA contracts, with implied Q4 revenue step-up; net loss improved YoY, and quarterly net loss narrowed sequentially into Q4 as spend and revenue timing shifted .
- Runway moved up to 4Q25 with cost actions; partnership/non-dilutive funding remains important to extend runway and advance programs amid stop-work uncertainty .
- Manufacturing readiness and pill-based logistics (stable shelf life, U.S. GMP) remain strategic advantages for pandemic preparedness and potential partnering .
- Near-term trading setup: Watch for stop-work resolution by ~90 days from Feb 21, 2025 and norovirus Phase 1 topline mid-2025; both could drive step-changes in narrative and risk profile .
